Q.With the kaolin clay to kill stinkbugs, will the soap burn my plants?
I have used dish soap to kill spider mites by washing the underside of leaves with soap and water. One time I did not rinse it well enough and killed my tomatoes. Is this a small enough amount (2 tsp) to 2 gallons of water with the kaolin that it won’t burn the plants? It sounds great to leave the kaolin on the leaves but am worried about the soap.
